    摘要： The present publication discloses a communication chip integrated with a SIM card, comprising: a baseband CPU, a first protocol interface, a selector switch, and a SIMZone unit; said baseband CPU being connected to the first protocol interface; said selector switch being connected to the SIMZone unit, the first protocol interface, and an IF1 interface. The selector switch and said SIMZone unit are always in a state of communication with each other, and when said selector switch is in a state of communication with said first protocol interface, said SIMZone unit is used for providing SIM card functionality to said baseband CPU; when said selector switch is in a state of communication with said IF1 interface, said SIMZone unit is used for receiving data written by means of said IF1 interface. In the embodiments of the present publication, by means of integrating a SIM card in the communication chip of a terminal equipment, the area occupied by the SIM card on the PCB of the terminal equipment is reduced, the SIM card is prevented from serving as an independent hardware entity, the swapping process is avoided, and reliability and security are increased, security being not lower than that of a conventional SIM card.

    摘要翻译： 本公开公开了一种与SIM卡集成的通信芯片，包括：基带CPU，第一协议接口，选择器开关和SIMZone单元; 所述基带CPU连接到第一协议接口; 所述选择器开关连接到SIMZone单元，第一协议接口和IF1接口。 所述选择器开关和所述SIMZone单元总是处于彼此通信的状态，并且当所述选择器开关处于与所述第一协议接口通信的状态时，所述SIMZone单元用于向所述基带CPU提供SIM卡功能; 当所述选择器开关处于与所述IF1接口通信的状态时，所述SIMZone单元用于接收通过所述IF1接口写入的数据。 在本公开的实施例中，通过将SIM卡集成在终端设备的通信芯片中，终端设备的PCB上的SIM卡占用的面积减少，防止了SIM卡作为 独立的硬件实体，避免交换过程，提高可靠性和安全性，安全性不低于传统SIM卡的安全性。
